In the midst of our busy lives, finding time for home improvement projects can be challenging, especially when it involves major tasks like installing a new HVAC system. If you’re wondering, “How long does it take to install a heat pump?” – we have you covered. HVAC.com explores what you can expect and the different factors that can influence the installation timeframe for a new heat pump system.

What’s the Typical Timeframe for Installing a Heat Pump?

On average, installing an air-source heat pump takes between 3 to 8 hours. However, this duration can vary widely based on several key factors.

Factors Influencing Heat Pump Installation Time

1. Type of Heat Pump: Air Source vs Ground Source

Air-source heat pumps, which exchange heat with the outside air, are generally quicker and easier to install than ground-source (geothermal) heat pumps. Ground source systems, which involve burying a network of pipes in the ground to exchange heat with the earth, require extensive excavation and additional installation work, leading to a longer setup time. Installing a geothermal heat pump can take several weeks once you factor in surveying the home and property.

2. System Size

The size of a heat pump can affect how long it takes to install. For example, larger heat pump systems, like a 4-ton unit, usually need more preparation and adjustments, which can make the installation process longer compared to smaller systems.

3. Existing Infrastructure

A major factor in determining how long a heat pump takes to install is whether your ductwork needs upgrading. Ductwork lasts about 10-25 years on average, so there’s a good chance your air ducts might need to be replaced when you buy a new HVAC system. Installing a heat pump with new ductwork can extend the duration from several hours to one or more days.

Meanwhile, older homes might need electrical system upgrades to accommodate the new heat pump, which can also extend the installation timeframe.

4. Space and Accessibility

The ease of access to the installation site also affects the time required to install a heat pump system. Tight or hard-to-reach areas may require additional effort and time to properly fit and secure the unit, while more accessible locations can streamline the installation process.

5. The Installer’s Experience

Hiring an HVAC installer with several years of experience can ensure the job is completed faster and more efficiently. Choosing a reputable company with stellar online ratings can help ensure the installation goes smoothly.

6. Additional Features

Installing heat pumps with two-stage or variable-speed compressors may add to the installation time due to the additional configuration and wiring involved in accommodating multiple operating models. Other add-ons or features that can increase the duration of heat pump installation include smart thermostats, zoning capabilities, and indoor air quality equipment such as dehumidifiers and whole-house air purifiers.

7. First-Time Installation or Replacement

A first-time installation of a heat pump in a home typically takes longer compared to replacing an existing system, as it involves additional steps such as setting up new ductwork or making structural modifications. The process requires more time for planning, installation, and ensuring that all components are correctly integrated into the home.

How to Plan for Heat Pump Installation

You can help to ensure a smooth installation of your new heat pump system. Start by clearing the installation area. Remove any obstacles or clutter around both the indoor and outdoor units to give the technicians easy access. This means moving furniture or personal items that might get in the way of their work.

Next, communicate any specific concerns or preferences you have about the installation with your HVAC contractor ahead of time. Informing them in advance about where you’d like the indoor unit placed or any scheduling issues will help avoid misunderstandings and ensure your needs are met.

Be ready to grant access to your property, provide information about your existing system, and secure pets during the installation. Also, plan to be available for post-installation testing to address any questions or issues.
